Hello Steve, Hello OpenSSH-portable developers, I am building OpenSSH for our (EBCDIC-based) BS2000 mainframe operating system, and I noticed you do the same for OS/390. Because my initial ssh port was based on IBM's OSS port (ssh-1.2.2 or some such), I thought it was fair enough to help with a little co-operation; we might come up with a unified EBCDIC patch which could be contributed to

Hi, About a year and a half ago I brought up the topic of encrypted hostkeys and posted a patch (http://marc.info/?l=openssh-unix-dev&m=132774431906364&w=2), and while the general reaction seemed receptive to the idea, a few problems were pointed out with the implementation (UI issues, ssh-keysign breakage). I've finally had some spare time in which to get back to this, and I've

Has anyone here managed to send files from a mobile phone to a CentOS system via Bluetooth? I'm trying with a Samsung E1310, using the GNOME tools, but can't get it to work. I can send files from the Linux box to this phone using the Nautilus bluetooth plugin (nautilus-sendto-bluetooth), and have also managed to "pull" some data I've been trying to send, via

Hi all, I recently made a patch to openssh 4.1p1 to allow it to use the in-kernel key management provided by 2.6.12 or later Linux kernels. I've attached the patch (which is still only a proof-of-concept, for instance its very verbose right now) to this mail. Now, my question is, is this a completely insane idea and would (a later version of) the patch have a chance of making it into the

this (uncomplete) patch makes various features compile time options and saves up to 24K in the resulting ssh/sshd binaries. i don't know whether this should be added to the CVS since it makes the code less readable. perhaps WITH_COMPRESSION should be added, since it removes the dependency on libz -m Index: Makefile.inc =================================================================== RCS

By the way, I noticed in the previous IdentityFile patch I forgot to expand tilde. I fixed this by making the change in ssh.c instead of readconf.c, which is probably where it belongs, as far as the existing code is concerned: diff -ur openssh-3.0.2p1/auth.c openssh-3.0.2p1I/auth.c --- openssh-3.0.2p1/auth.c Sun Nov 11 17:06:07 2001 +++ openssh-3.0.2p1I/auth.c Sun Jan 27 12:05:14 2002 @@ -44,7

Here is a patch to allow private key files to be placed system wide (for all users) in a secure (non-NFS) mounted location on systems where home directories are NFS mounted. This is especially important for users who use blank passphrases rather than ssh-agent (a good example of where this is necessary is for tunnelling lpd through ssh on systems that run lpd as user lp). IdentityFile now accepts

Here is the user-dependent IdentityFile patch for openssh3.5 (BSD version), which allows private key files to be placed system wide (for all users) in a secure (non-NFS) mounted location. This addresses an important security hole on systems where home directories are NFS mounted, particularly if there are users who use blank passphrases (or when lpd is tunneled through ssh on systems running lpd

interacts with the telnet/rlogin server on AIX. The previous entries about this only starting at ML03 and above seem to be correct. The bug is not triggered in earlier versions of AIX. Unfortunately, I have been unable to create a test case program that causes the hang to occur. However, a simple hack to channels.c does seem to fix the problem: --- channels.c.orig Tue Jul 2 14:34:32 2002 +++

I'm in the process of updating my GSSAPI patches to the 2.9 release. However, I've run into a slight problem with managing to get user options to play nicely with the way that the kex code is now organised. With the GSS kex its possible for the user to specify whether they want to delegate their credentials to the server or not. This option is used only on the client side (and so is

Dear all, I am currently implementing an experimental key exchange (KEX) algorithm. Unlike current algorithms like DH, mine needs to be able to fail gracefully, and in case of failure, continue with whatever algorithm would have been negotiated if mine was not selected. My strategy for graceful failure is to remove my KEX algorithm from myproposal[KEX_DEFAULT_KEX] and to initiate a new key

I have a few patches for AIX. The patchfile is attached below. The patch has been tested on AIX4.2 and AIX4.3. The patch is on openssh-1.2.1pre25, with openssl-0.94, using RSAref. 1) authenticate support - this function allows the system to determine authentification. Whatever the system allows for login, authenticate will too. It doesn't matter whether it is AFS, DFS, SecureID, local.

Hey guys, My second post in the last few days (boy I'm active! ;)). We've had a few issues with SSH Secure Shell version 3.2.0 (build 267) and sftp and while trying to figure it out I noticed something in the debug output that I think should be brought to OpenSSH's attention. Ssh2Transport/trcommon.c:1518: All versions of OpenSSH handle kex guesses incorrectly. Does anyone know

Hello, since one currently (after the 9.6 release addressing terrapin with strict-kex) cant be sure that strict KEX mode is negotiated (it depends on the capabilities of the partner), and the mitigation for that is to disable most modern/alternative ciphers and MAC modes - I would suggest you offer the option to enforce strict-kex mode as a server config as well as a per-host config in the
